What is the size of Class C airspace?

Although the configuration of each Class C airspace area is individually tailored, the airspace usually consists of a 5 NM radius core surface area that extends from the surface up to 4,000 feet above the airport elevation, and a 10 NM radius shelf area that extends no lower than 1,200 feet up to 4,000 feet above the ...

VFR aircraft also must maintain a horizontal distance of 1sm from clouds while operating in Class E at and above 10,000ft. Below 10,000ft, the increase in TAS is reduced due to the lower altitudes. Therefore, the minimum forward flight visibility can be reduced from 5sm to 3sm.
